Predictors of home- vs . facility-based delivery among women living in rural Niger
Background: Niger has one of the highest maternal mortality rates, and facility delivery can help prevent these deaths. While distance to health facilities predicts home delivery in other sub-Saharan African settings, few studies have examined this relationship in Niger. Methods: This cross-sectional survey, an ancillary study to the AVENIR trial, included women aged 12-59 years old with a child participating in a sub-trial of AVENIR. Trained wor…
Seasonality of underweight among infants 1–11 months old in Niger
INTRODUCTION: Malnutrition is a risk factor for child mortality, with around 45% of deaths in children under 5 globally linked to malnutrition. Seasonality of malnutrition has important implications for the timing of child health programme activities, but evidence is mixed on the nature of such patterns. Moreover, the bulk of the existing evidence is focused on wasting and stunting in children 6-59 months, despite increasing evidence that younger…
Mass azithromycin for prevention of child mortality among children with acute malnutrition
Children with acute malnutrition are at high risk of morality. Mass azithromycin distribution reduces all-cause mortality among children aged 1–59 months, and effects may be greater in underweight infants. Here, we evaluate the efficacy of azithromycin for reducing all-cause mortality in children aged 6–59 months with acute malnutrition (mid-upper arm circumference, MUAC, P -value for interaction on the relative scale = 0.09; P -value for interac…
Age-based targeting of biannual azithromycin distribution for child survival in Niger
This trial was registered on January 13, 2020 (clinicaltrials.gov: NCT04224987 )
Comparison of anthropometric indicators to predict mortality in a population-based prospective study of children under 5 years in Niger
Objective: In the present study, we aimed to compare anthropometric indicators as predictors of mortality in a community-based setting. Design: We conducted a population-based longitudinal study nested in a cluster-randomized trial. We assessed weight, height and mid-upper arm circumference (MUAC) on children 12 months after the trial began and used the trial’s annual census and monitoring visits to assess mortality over 2 years. Setting: Niger. …
The role of vaccination coverage, individual behaviors, and the public health response in the control of measles epidemics
The simulation results demonstrated the importance of vaccination coverage, clustering of immunity, and contact investigations in preventing uncontrolled measles outbreaks
Integrating Disease Control Strategies
Objectives. Although the burden of diarrheal disease resulting from inadequate water quality, sanitation practices, and hygiene remains high, there is little understanding of the integration of these environmental control strategies. We tested a modeling framework designed to capture the interdependent transmission pathways of enteric pathogens. Methods. We developed a household-level stochastic model accounting for 5 different transmission pathw…
Assessing the validity of tuberculosis surveillance data in California
For most variables examined on the TB case report, data validity was excellent, indicating a robust surveillance system. However, lower data quality was noted for a small number of variables primarily impacting treatment adherence, including assessment and planning; advocacy; allocation and garnering of resources; and research. The study provides compelling evidence supporting the CDC workgroup's proposed revisions to the TB case report
Cost-effectiveness of tuberculosis evaluation and treatment of newly-arrived immigrants
Background Immigrants to the U.S. are required to undergo overseas screening for tuberculosis (TB), but the value of evaluation and treatment following entry to the U.S. is not well understood. We determined the cost-effectiveness of domestic follow-up of immigrants identified as tuberculosis suspects through overseas screening. Methods Using a stochastic simulation for tuberculosis reactivation, transmission, and follow-up for a hypothetical coh…
Logistics of community smallpox control through contact tracing and ring vaccination
Small introductions of smallpox are likely to be easily contained by ring vaccination, provided contact tracing is feasible. Uncertainties in the nature of bioterrorist smallpox (infectiousness, vaccine efficacy) support continued planning for ring vaccination as well as mass vaccination. If initiated, ring vaccination should be conducted without delays in vaccination, should include contacts of contacts (whenever there is sufficient capacity) an…
Leprosy and tuberculosis
OBJECTIVES: This study tested the hypothesis, first proposed by Chaussinand, that individual-level immunity acquired from exposure to tuberculosis may have contributed to the disappearance of leprosy from western Europe. METHODS: The epidemiological consequences of cross-immunity were assessed by the formulation of a mathematical model of the transmission dynamics of tuberculosis and leprosy. RESULTS: The conditions under which Mycobacterium tube…
